General Information

Tempo 20 WP insecticide contains 20% active ingredient, which will provide effective knockdown and residual control of the pests listed in the label.

One level Tempo scoop or 4 level teaspoons contain 9.5 grams of Tempo 20 WP. Do not use scoop or teaspoon for feed, food, or drinking water purposes.

Tempo 20 WP is intended for use as an indoor spot, or crack and crevice application in Dwellings, such as apartments, hospitals, hotels, houses and nursing homes; Institutions, such as factories, laboratories, mausoleums, non-commercial greenhouses, schools, stores and warehouses; Modes of transport, such as aircraft, buses, rail cars, ships and trucks; Food/feed establishments, such as bakeries, bottling plants, canneries, dairies, frozen food plants, grain mills, kitchens, meat packing plants, poultry and egg processing plants and restaurants; and Pet kennels.

Tempo 20 WP also is intended for use as a general surface spray for control of flying and crawling insects in livestock housing structures, including poultry houses.

Tempo 20 WP is intended to be mixed with water and applied with hand pressurized or power operated sprayers. Spray pressure should not exceed 345 KPa (50 psi) at the nozzle tip when used indoors. Add the appropriate amount of product when filling sprayer tank with water, shake or agitate as necessary to mix. Diluted spray mixture can be stored overnight and applied the following day, but the mixture should be agitated before spraying to prevent uneven distribution of product. Before leaving spray mixture unagitated for an extended period of time, release tank pressure and elevate nozzle and hose above tank outlet, activate trigger and drain all suspension from hose back into spray tank. Re-tighten spray tank lid and do not re-pressurize until starting to spray again.

Tempo 20 WP will not stain or cause damage to any painted or varnished household surface, plastic, fabric or other surface where water applied alone causes no damage.

Spot, Crack And Crevice Applications

Mix one level Tempo scoop of Tempo 20 WP in 3.75 L of water to make a 0.05% active ingredient suspension. Under conditions of severe pest infestation or when longer residual control is needed, mix two level Tempo scoops of Tempo 20 WP in 3.75 L of water to make a 0.1% active ingredient suspension. Use a low pressure system with a pin-point or variable pattern nozzle to apply the suspension in specific areas such as cracks and crevices in or behind baseboards, in floors, walls, expansion joints, areas around water and sewer pipes, wall voids, or voids in table legs and equipment where pests can hide. Tempo 20 WP can be reapplied at 10-day intervals, if necessary. Do not apply where electrical short circuits could occur. Use a dust or dry bait in these areas. Spot treatment with a low pressure coarse spray may be made ONLY to localized areas along baseboards; beneath and behind sinks, stoves, refrigerators and cabinets; around plumbing and other utility installations; around doors and windows. A spot is an area no larger than 0.2 m2. NOTE: CARE SHOULD BE TAKEN TO AVOID DEPOSITING THE PRODUCT ONTO SURFACES WHICH ARE EASILY ACCESSIBLE BY CHILDREN.

Food/feed Establishments:

Tempo 20 WP applications are permitted in both food and non-food areas of food/feed handling establishments as a spot, or crack and crevice treatment. Food/feed establishments are defined as places other than private residences in which exposed food or feed is held, processed, prepared or served. Included also are areas for receiving, storing, packing (canning, bottling, wrapping, boxing), preparing, edible waste storage and enclosed processing systems (mills, dairies, edible oils, syrups) for food or feed. Serving areas where food is exposed and the facility is in operation are also considered food areas.

Application in food handling areas of the facility may be made during close-down periods only. Do not apply directly to food or food-handling surfaces. Cover or remove all food processing and/or handling equipment before application. After application in food processing plants, bakeries, cafeterias and similar facilities, wash all equipment, benches, shelving and other surfaces which food will contact. Clean food handling or processing equipment and thoroughly rinse with clean, fresh water.

Dwellings, Institutions And Modes Of Transport:

For general household pests and occasional invaders make applications in a manner as previously described under Spot, Crack and Crevice Application. Particular attention should be given to treating entry points and harbourage areas. Remove or tightly cover fish tanks and disconnect aerators during application. Bystanders and animals must be excluded during applications of Tempo 20 WP, and not allowed to re-enter treated areas until at least two hours afterwards.

For pantry pest control of exposed adult and immature stages of insects, make application to cupboards, shelving and storage areas. Particular attention should be given to treating cracks and crevices. Remove all utensils, uncovered foodstuffs (or any with package opened), shelf paper and other objects before spraying. Allow treated surfaces to dry and cover shelves with clean paper before replacing any utensils, foodstuff or other items. Any foodstuff accidentally contaminated with spray solution should be discarded.

For stored product pest control of exposed adult and immature stages of insect pests, apply to cracks, crevices, and other surfaces where the pests have been seen or have harbourage. Treat warehouses, production facilities, storage areas, rail cars, truck beds and other areas where products are stored before filling with the product. Tempo 20 WP may be used by pest control operators and grain producers to treat grain storage facilities and other areas noted above for stored product pest control. Cleaning of all areas prior to use of Tempo 20 WP will increase levels of control. Any foodstuffs infested with pests should be removed and destroyed.

For premises pest control make spot application in closets and storage areas where these pests normally feed or hide. Follow all precautions listed above for general household pests.

For control of carpet beetles, apply as a spot treatment along baseboards and edges of carpeting, under carpets and rugs, in closets and on shelving.

For control of flying insects indoors, apply as a spot treatment on window frames. Do not apply as a “space spray”.

For control of carpenter ants in houses and other structures, use a 0.1% suspension and apply as a spot, crack and crevice or wall void application. Repeat treatments when necessary. Apply around doors and windows. Spray into cracks and crevices or through small drilled holes into voids where these ants or their nests are present. Do not exceed 30 to 50 mL of dilute suspension per m2 of treated surface.

For aircraft pest control apply to cracks, crevices and other surfaces where the pests have been seen or have harbourage. Applications should not be made when passengers or non-essential personnel are present in the immediate or treated area. Passengers or other personnel should not be allowed to enter treated areas until at least two hours after application. Do not use in aircraft cabins. Do not allow spray to contact electrical and electronic systems.

Pet Kennels:

For use in pet kennels to control flying and crawling insects: apply as a spot or crack and crevice spray. Control will be enhanced when facilities are cleaned. Do not make applications of Tempo 20 WP when animals are present in area of facility to be treated. Allow at least two hours after application before re-stocking treated area of the facility. Cover or remove animal feedstuffs or watering equipment.

General Surface Applications

Livestock Housing (including Poultry Houses):

For use by pest control operators and livestock producers in livestock housing structures (including poultry houses) to control crawling and flying insect pests. For control of flies apply as a general surface spray using 1 or 2 level scoops of Tempo 20 WP per 100 m2 in sufficient water to adequately cover the area being treated, but which will not allow dripping or run-off to occur. Use the higher rate when infestation is severe or when longer residual control is needed. Use a low pressure spray system with a fan-type nozzle to uniformly apply the suspension. Control will be enhanced if facilities are cleaned. Applications can be made to all fly resting surfaces such as walls, ceilings, posts, rafters, windows, dividers, stanchions, gates, bunks, curtains, etc. Full protective clothing is recommended, including a hat (preferably safety helmet with visor), safety glasses, goggles or face shield, respirator, long-sleeved coveralls, unlined rubber gloves and rubber boots. Do not apply Tempo 20 WP when animals are present in area of facility to be treated. Apply only in well ventilated areas. Do not allow cattle to re-enter facilities within 2 hours following application and poultry within 24 hours following application. Cover watering bowls in dairy barns securely with a tight fitting, elastic banded plastic cover. Cover feeding troughs in dairy barns securely with heavy plastic (6 mil) with sufficient plastic to allow for a 6" overhang on the sides of the trough. Avoid direct spray application to the plastic used to cover bowls and troughs. Allow two hours after application before restocking treated area of facility. Do not apply where electrical short circuits could occur. Do not apply as a “space spray”.

For control of crawling pests (see list) apply as a surface spray (see all the above directions and precautions for fly control) and/or as a crack and crevice application (0.05-0.1% active ingredient suspension) to areas where the insects occur. For control of lesser mealworm (adults and larvae) in poultry houses apply after clean-out and before fresh litter is put down. Do not add fresh litter until at least one day after spraying.

Resistance Management

Tempo 20 WP is a synthetic pyrethroid (Group 3) insecticide. Any insect population may contain individuals naturally resistant to Tempo 20 WP and other Group 3 insecticides. The resistant individuals can dominate the insect population if these insecticides are used repeatedly. These resistant insects will not be controlled by Tempo 20 WP or other Group 3 insecticides.

To delay insecticide resistance, avoid the exclusive, repeated use of Tempo 20 WP or other insecticides in the synthetic pyrethroid group. Integrate other control methods (chemical, biological, good sanitation practices) into insect control programs whenever practical. Keep accurate records of insecticides used in each location.


1. Crawling Pests: Ants (except Pharaoh); Bedbug; Carpet beetles; Cockroaches: American, German, Oriental; Crickets; Lesser Mealworm (adults & larvae); Earwigs; Firebrat; Sowbugs; Spiders

2. Flying Pests: Flies, Mosquitoes, Wasps

3. Pantry & Stored Product Pests: Beetles (exposed adults & immature stages): Confused flour, Warehouse; Moths: Indian meal (larvae only)

4. Wood Infesting Pests: Carpenter ants
